ffmpeg : Combine/merge multiple mp4 videos - not working
9 juin 2016, par dtbakerHere is the command I am using to combine multiple videos :
ffmpeg -i 75_540_38HQ2.mp4 -i 76_70_20.mp4 -i 76_173_80.mp4 -i 81_186_35.mp4 -vcodec copy -acodec copy Mux1.mp4
The resulting
Mux1.mp4
does not contain all videos. Only the first video (75_540_38HQ2.mp4
). The file size of the source and resulting video is below (as you can see, resulting video is slightly larger than first vid) :$ ls -lh

Edit : couldn’t solve it so I just use avidemux GUI tool. It seemed to append the MP4’s just fine.
Must be a problem with MP4’s or just the ones that come off a gopro camera.

Am I doing something blindingly stupid here ?



The source videos came from a video camera, and are small snippets taken with
ffmpeg -i bigfile.mp4 -ss 20 -t 10 -vcodec copy etc..



Thanks heaps !!
Dave





Edit : couldn't solve it so I just use avidemux GUI tool. It seemed to append the MP4's just fine.



Must be a problem with MP4's or just the ones that come off a gopro camera.
